Problems solved by technology

[0002] In agriculture, when spraying pesticides, it is necessary to atomize the pesticides and then spray them out. The function of the nozzle is to atomize the pesticides. The existing atomizing nozzles are expensive, heavy, easy to damage, and the flow rate cannot be adjusted. The atomized droplets Not fine enough, and the connection between the pipe and the nozzle is easy to fall off, the disassembly and assembly of the drug delivery pipe is inconvenient, and it is not easy to clean

Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 An embodiment of the present invention shown is composed of a nozzle cover 1 , a flow regulating rod 2 , a knob cap 3 , a vortex generator 4 , a water pipe 5 and a water pipe adapter core 6 . Wherein the nozzle cover 1 is made of plastic, which is characterized by lightness and low cost, and is easy to form. The top of the nozzle cover 1 is provided with a spout 11, and the spout 11 is in the shape of an annular boss. The shape of the shrinking nozzle tube, the minimum inner diameter is 18mm, which is obtained through experiments to ensure that the size of the sprayed water droplets can be minimized; the tail of the nozzle cover 1 is connected to the air duct, and there is a protruding bone at the connection between the tail and the air duct. Position 13, the connection between the nozzle cover 1 and the air duct is fixed by a ...

Abstract

The invention provides a handheld spray head, and relates to the technical field of spray heads of spraying machines. The handheld spray head is characterized by comprising a spray head cover, a flowadjusting rod, a knob cap, a vortex generator, a water pipe and a water pipe switching core, wherein a spray nozzle is arranged on the top of the spray head cover, and the tail part of the spray headcover is connected with the air pipe, and a handheld handle is arranged in the middle of the spray head cover; the water pipe is arranged in the spray head cover, a water outlet of the water pipe is connected with the vortex generator, a water inlet is connected with the water pipe switching core, and the water pipe switching core is connected with the drug delivery pipe in the air pipe; the flowregulating rod is connected with the vortex generator to regulate the water flow of the water pipe, and the knob cap sleeves the flow regulating rod; and the vortex generator is arranged at the spraynozzle. According to the handheld spray head, the design of the spray nozzle can ensure that the sprayed water mist is finer, the flow can be accurately adjusted, and the handheld spray head has the working characteristic of being suitable for ultra-low-volume pesticide application. Furthermore, a manufacturing method of the handheld spray head is provided, and the handheld spray head is manufactured through blow molding, and is light in weight, low in cost and compact in structure.

Description

[technical field] [0001] The invention relates to the technical field of sprayers, in particular to the technical field of sprayer nozzles. [Background technique] [0002] In agriculture, when spraying pesticides, it is necessary to atomize the pesticides and then spray them out. The function of the nozzle is to atomize the pesticides. The existing atomizing nozzles are expensive, heavy, easy to damage, and the flow rate cannot be adjusted. The atomized droplets It is not fine enough, and the connection between the pipe and the nozzle is easy to fall off, and the disassembly and assembly of the drug delivery tube is inconvenient, and it is not easy to clean. [Content of the invention] [0003] In order to overcome the defects of the prior art, the present invention provides a hand-held spray head which is light in weight, low in cost, and can adjust the flow rate, and further provides a manufacturing method of the hand-held spray head. [0004] A hand-held nozzle, charact...
